H11: section a through f - the information provided by bd represents all of the known information at this time.Despite good faith efforts to obtain additional information, the complainant / reporter was unable or unwilling to provide any further patient, product, or procedural details to bd.Based on a review of available complaint information and an evaluation of the available sample evidence, the following was concluded: the complaint of the introducer peeling upon insertion is confirmed and was determined to be due to an unknown cause.One 3.5 fr microintroducer was returned for evaluation.An initial visual observation showed blood use residues throughout the microintroducer.There were no obvious sharp bends observed on the returned device, but the distal tip of the gray sheath appeared deformed.A microscopic observation revealed the entire distal tip of the gray sheath to be deformed and pushed towards the proximal end of the microintroducer.Nothing remarkable was observed throughout the rest of the complainant device.The complaint of peeling the microintroducer upon insertion of the device is confirmed.Due to the extent of the deformation, a cause cannot be established as the microintroducer had abundant use residues and deformation to the distal tip of the gray sheath.Possible causes may be angle of insertion of the device or a sharper taper angle due to the manufacturing process of the device.
